GEORGE F. HOEFFER, OF CHICAGO, ILLINOIS.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 251,779, dated January 3, 1882,

' Application filed November 21,1881. (No model.)

T all whom it may concern Be it known that I, GEORGE F. HOEFFER, a citizen of the United States, residing atGhicago, in the county of (look and State of Illinois, have invented a-new and useful Improve,

ment in Bottle-Stoppers, (which has not been patented to myself or to others, with my consent or knowledge, in any foreign. country;) and I do hereby declare the following to be a clear, full, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification. Like letters and figures refer to like parts wherever they occur.

My invention relates to an improvement in bottle-stoppers for closing bottles of all kinds in a quick and secure manner and the object of said inventionis to obtain such a construction of the stopper that, in combination with a stopper-yoke and its lever, it will efiect a double corkage, one upon the mouth and lips and the other Within the throat of the bottle; to which end said stopper consists of two (a large and a small) circular centrally-perforated concaved metal plates, and of a cone-shaped hollow rubber bulb having at its top a thick interiorly grooved flange, the upper. portion of which is fastened between said plates by means of a screw passing through the perforations of said plates into a concaved wooden button inserted into the cone-shaped cavity of said bulb. a

I will now proceed to describe my invention, so that others skilled in the art to which it appertains may apply the same.

In the drawings, Figure I indicates the large concaved circular plate, made of galvanized sheet-iron, and perforated in the center a. Fig. II indicates the small concaved circular plate, made of sheet-iron, and perforated in the center b. Fig. III indicates the concaved button, made of wood, with a small perforation through the center 0 for the guidance of the screw shown in Fig. IV. Fig. 1V indicates the screw, made of galvanized wire, and hav-- bottle. Fig. VIII indicates a central vertical section of the stopper, showing all of theparts as they appear together in position in the stopper. I

The stopper is constructed as follows: Insert the wooden button into the cone-shaped cavity of the bulb, and place upon it the small plate with its convexed side resting upon the concaved surface of said button and its edge extending into the groove n a of the flange of said bulb. Then place the large plate, wit-h its concaved side down, upon the upper surface of said flange, and, passing the screw through the perforations of said plates, screw the same tightly into said wooden button, thereby fastening the upper portion of said flange firmly between the edge of said small plate and the inside surface of the large plate.

The advantages of my invention are that the rubber bulb can never become disconnected from the plates and lost, that the stopper can be increased to any reasonable size by merely increasing the diameter of the button, and that the stopper effects a corkage upon the mouth and lips as well as within the throat of the bottle.

The devices may be operated as follows: To close a bottle, place the stopper upon the mouth of the bottle and push the locking-lever R up against the head of the vessel, thus bringing the yoke F F into line, and forcing the coneshaped portion of the stopper tightly into the throat and the flange firmly upon the mouth and over the lips of the bottle.

I do not herein claim the combination,with a bottle-stopper, of a locking-lever pivoted to the bottle Within its length, and a stopper-yoke pivoted to the free ends of a locking-lever but,

Having described my inveution,what Iclaim as new, and desire to secure by Letters Patent, 1s

1 The elastic stopper-bulb with an iutericone-shaped hollow elastic bulb having an in- 10 Orly-grooved flange fastened between two cirteriorly-grooved flange, by the upper portion cular centrally perforated coneaved metal of said flange being fastened between said plates by a screw passing through thepert'orai plates, substantially as before set forth. tions of said plates into a wooden concaved button resting in the cone-shaped cavity of GEORGE HOEFFEP' said bulb,substantially as shown and described. I Witnesses 2. The combination of two circular centrally- UHAS. E. GAYLORD, perforated concaved metal plates, with the B.TOWNSEND.
